Technical Integration Engineer - TS/SCI with Poly

Leidos is seeking a highly skilled Technical Integration Engineer (TIE) to join our dynamic team. This hybrid role combines the expertise of a Systems Administrator, Software Engineer, and Information Systems Security Engineer (ISSE) to design, implement, and maintain complex technical solutions that drive mission success. The Technical Integration Engineer will play a critical role in integrating systems, ensuring security compliance, and developing software solutions to support enterprise-level projects. As a Technical Integration Engineer, you will work in a collaborative, fast-paced environment, bridging the gap between system administration, software development, and cybersecurity. This position requires a versatile professional who thrives in solving multifaceted technical challenges and delivering innovative, secure, and scalable solutions.

Duties include software requirements analysis, analysis of hardware compatibility, development of software products and tools used for design, development and maintenance of infrastructure, and platforms. The candidate will also be responsible for certified network and system administration on GEOINT and SIGINT lab hardware, software, databases, and managed network systems to ensure availability and reliability of operations within lab environments (including Linux, Microsoft Office, and other lab operating systems as required). Additional responsibilities include technical planning, technical design, development and integration of external capabilities, and verification and validation.

The successful candidate will influence development of solutions that impact strategic lab goals and results. He or she will recommend and develop new technical solutions, products, and/or standards in support of lab strategy and operations. He or she will lead and manage other technical staff in implementing technical solutions that will have significant impact on lab project results/outputs. The candidate will work to convince others to accept lab's view/current practices and agree/accept new concepts, practices and approaches.

The candidate will be responsible for issue investigation and resolution and installing new software baselines at lab locations. The candidate will interface with program, lab, and site leadership regarding critical matters impacting the lab and its infrastructure, as well as project managers, systems engineers, and software developers on a regular basis, so good communications skills are a must. Candidate will be a self-starter with excellent organization and leadership skills.
